This is an invited commentary on “Risk Transmission Across Supply Chains” by Sheridan Titman.

Electric power restructuring offers a major change to the vertically integrated monopoly. The change manifests the main part of engineers’ efforts to reshape the three components of today’s vertically integrated monopoly: generation, distribution and transmission. In a restructured environment, the main tasks of these three components will remain the same as before, however, to comply with ...

this paper uses a multivariate garch model to simultaneously estimate the mean and conditional variance using daily returns among different tehran sector indexes from tir 1386 to tir 1391. since different financial assets are traded based on these sector indexes, it is important for financial market participants to understand the volatility transmission mechanism over time and across sectors in...

As first steps towards establishing software engineering as an engineering discipline, we need to create explicit models of its building blocks, i.e., projects, processes, products, and various quality perspectives; organize these models for effective reuse across project boundaries; and establish measurable criteria for project guidance. This paper investigates the possibilities of providing m...

We use highway procurement auction data to analyze the California Small Business program that awards a contract to a qualified small bidder provided its bid is within five percent of the overall low bid. We study the effect of this rule on bidders’ incentives to participate in procurement auctions and compute its implied efficiency and distributional costs. Small bidder can use the discount to ...

Distributed Generation (DG) is increasing in penetration on power systems across the world. In rural areas, voltage rise limits the permissible penetration levels of DG. Another increasingly important issue is the impact on transmission system voltages of DG reactive power demand. Here, a passive solution is proposed to reduce the impact on the transmission system voltages and overcome the dist...
